tomcat9 - Tomcat 服务未使用弹性 APM java 代理启动

问题描述

我正在尝试使用弹性 APM 代理（java）在 linux 中启动 tomcat 服务。但是每次我启动服务时，都会出现这些错误

我正在使用以下命令为 APM 代理设置环境变量

export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/app/elastic-apm-agent-1.23.0.jar"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.service_name=Stage-pricing"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.application_packages=org,com,com.qr.jadu"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.server_url=http://ip:8200"
export CATALINA_OPTS="$CATALINA_OPTS -Delastic.apm.global_labels='env=Stage'"

和 logback-classic 版本 1.0.6

请提出解决方案或我缺少的任何步骤，在此先感谢。

解决方案

Caused by: java.lang.VerifyError: (
  class: javax/servlet/GenericServlet,
  method: init
  signature: (Ljavax/servlet/ServletConfig;)V)
invokedynamic bytecode is not supported in this class file version

彼得是对的。您的 Elastic APM 代理 - 无论做什么 -void GenericServlet.init(ServletConfig)以利用invokedynamic字节码指令的方式转换字节码，而不是检查或期望它编织成的代码来自古老的 Java 版本。Invokedynamic 是在 Java 7 中引入的，因此您的 JAR 必须包含旧版本。如果可以通过这种方式配置代理，则将其从转换中排除，或者升级 JAR，使用更新的版本或将 API 源重新编译到更新的 (Java 7+) 字节码版本。大多数代理可能更期待 Java 8+，但我不确定你的。
